You can have a trigger that calls on apex code when a record updates/inserts.
Or you can have buttons that invoke apex.
Thanks
When Should I Use Apex?
Apex is a strongly typed, object-oriented programming language that allows developers to execute flow and transaction control statements on the Force.com platform server in conjunction with calls to the Force.com API. Using syntax that looks like Java and acts like database stored procedures, Apex enables developers to add business logic to most system events, including button clicks, related record updates, and Visualforce pages. Apex code can be initiated by Web service requests and from triggers on objects.
Apex
Use Apex if you want to:
Create Web services.
Create email services.
Perform complex validation over multiple objects.
Create complex business processes that are not supported by workflow.
Create custom transactional logic (logic that occurs over the entire transaction, not just with a single record or object).
Attach custom logic to another operation, such as saving a record, so that it occurs whenever the operation is executed, regardless of whether it originates in the user interface, a Visualforce page, or from SOAP API.
Visualforce
Visualforce consists of a tag-based markup language that gives developers a more powerful way of building applications and customizing the Salesforce user interface. With Visualforce you can:
Build wizards and other multistep processes.
Create your own custom flow control through an application.
Define navigation patterns and data-specific rules for optimal, efficient application interaction.
